Problems solved by technology
The existing electric power steering system does not have the function of intelligently protecting knees and feet. Compared with mechanical power steering column products, electric power steering column products are due to the addition of a booster motor and electronic control of the steering column in front of the driver. Protruding objects such as units are likely to cause impact on the driver's knees and feet during the collision process, causing damage to the driver's knees and feet

The invention discloses a control method of a knee and foot protection system of a vehicle, a knee and foot protection system and a vehicle. The control method includes the following steps: detecting a front-side collision pressure value of the vehicle, and controlling the vehicle to open the vehicle knee according to the front-side collision pressure value Foot protection system; obtain driving information of the vehicle, the driving information includes: the front side collision pressure value of the vehicle and / or the vehicle deceleration signal value and / or the braking pressure value of the vehicle brake pedal and / or the accelerator pedal pressure value and / or the column crushing stroke value and / or the steering column rotation angle value; determine whether the driving information meets the predetermined conditions according to the driving information; if so, control the protection device of the vehicle knee foot protection system to open the Knee and / or foot protection. Therefore, through the control method, the steering column electronic control unit, the booster motor and the accelerator pedal can be prevented from impacting the driver's knees and feet when the vehicle collides, and the personal safety of the driver can be ensured.
Description
technical field [0001] The present invention relates to the field of vehicles, in particular to a control method of a knee and foot protection system of a vehicle, a knee and foot protection system and a vehicle. Background technique [0002] With the development of the vehicle industry, vehicle safety has been paid more and more attention. The regulatory requirements in different vehicle markets (Europe, USA, Asia) and the crash-related requirements for driver safety are constantly increasing, and the vehicle's protection system must provide optimal protection for drivers of any size in a short period of time. With the development of EPS (Electric Power Steering, electric power steering system) electronic control technology, airbag control technology, and electronic control unit multi-control coordinated control technology, the coordination of the above three technologies is possible. [0003] Among the related technologies, the mature electric power steering column produc...
